- Efficient Teams A coding competition is being organized on the HackerRank platform. The participants need to be grouped into teams where each team has exactly two candidates. There are n candidates, where each candidate has a skill denoted by skill[i]. A total of ( n/2) teams are to be formed, such that the total skill of each team is the same. The efficiency of a team is defined as the product of the skill levels of its two members, i.e., for the-skills [1, 3], the efficiency of the team is 1∗3=3. Find the sum of efficiencies of all teams that can be formed satisfying the criteria. If there is no way to create teams that satisfy the conditions, return −1. Note: It can be shown that the answer is always unique. Example The skills of the candidates are skill =[1,2,3,2]. They can be paired as [[1, 3], [2, 2]]. The sum of skills for each team is the same, l.e., 4. The efficiency is computed as: - Efficiency of [1,3]=1∗3=3 - Efficiency of [2,2]=2∗2=4 Return the sum of efficiencies, 3+4=7.
